It’s relaxing to watch, fun to build, and surprisingly easy if you have a 3D printer! In this video, I take you through the full build — from 3D designing the parts in Fusion 360, to printing, assembling the electronics, coding the ESP32-C6, and finally testing it with real sand… well, actually salt + turmeric because I couldn’t find white sand in my town. STL FIles and Codes: https://cults3d.com/en/3d-model/home/... This project uses: ESP32-C6: https://www.waveshare.com/esp32-c3-ze... N20 motor with integrated driver: 15RPM ARGB LED strip: Genric You can control this gadget entirely from your phone: speed, direction, LED colors, effects, and more!
